IMPROVEMENT lN LEATHER-CHANNELING MACHINES.

Specification forming part of Letters Patent No. 173,687, dated February15, 1876, application filed have invented certain new and useful Im-'provements in Leather-Channeling Machines; and do hereby declare thatthe following is a full, clear, and exact description thereof, ref--erence being had to the accompanying drawings, and to the letters ofreference marked thereon, making a part of this specification.

Our invention relates to machines for channelin g leather for round workand it consists in a machine for channeling bothsides at the same time,whatever width the leather may be, and also in the construction andcombination of parts, as will be hereinafter more fully set forth. Inorder to enable others skilled in the art to which our inventionappertains to make and use the same,- we will now proceed to describeits construction and operation, referring to the annexed drawing, inwhich-- Figure 1 is a side elevation, and Fig. 2 a

plan view, of our machine tudinal vertical section of the same throughthe line xx, Fig. 2; and Fig. 4 is a transverse vertical section throughthe line 2 y, Fig. 2.

A represents'the bed ofonr machine, formed with a longitudinalslot, asshown in Fig. 4, for One of these heads, B, is stationary in thebed-plate, while the other head, B, is movable therein to and from thestationary head, and fastened at any pointdesired by means ofaset-screw, O. The top of each head B is made level along the inner edgeon top, while the remainder of the uppersurface is inclined downward, asshown. On this inclined part of the head is secured a plate, D, fastenedthereto by screws a a. In the center of this plate, on the under side,is made a longitudinal groove, in which is placed a knife, b, held bymeans of a setscrew, (1. This knife projects in an inclined position outover'the level part of the head,- Fig. 3. From the plate D, near theinner end, projects a vertical rod, E, on which is first placed aninclined collar, 0, and on top of the same is placed the foot G, whichextends down in front of the plate 1) above the point of the knife.Above Fig. 3 is a longi- August 14, 1875.

the foot G on the rod E is placed a spiral spring, and a nut, h, is thenscrewed on the end of the rod, to regulate the tension of said spring onthe foot. The adjustable head B, having been moved the desired distancefrom the stationary head, according to the width of the leather to bechanneled, is fastened by means of the set-screw O. The leatheris thenplaced on the flat portions of the heads B B, against the front ends ofthe'plates D D, and by being drawn through between them the knives b I)cut the channels in the two edges of the leather at the same timeUnderthe' point'of the knife in each head is a groove, .20, runningacross the head to receive the edge of the leather and keep the channelopen. The leather, as itpasses through the machine, is heldby the feet GG, which are raised, when desired, by means of a handle or lever, 70,projecting from the collar 6, so as to turn the same on the inclinedplate D.

Having thus fully LettersPatent, is l. The combination of the head B,grooved plate D,channeling knite b, and set-screw cl, substantially asand for the purposes herein set forth.

2. The combination of the inclined plate D, with rod E, collar 6, withhandle 70, foot Gr, spring f, and nut h, substantially as and for thepurposes herein set forth.

3. The head B, provided with the groove w upon its upper surface,scribed. I

at. The combination, with the slotted base A, of the stationary head B,with plate D, adjustable channeling-knife b, and yielding foot G, andthe movable head B, with similar for the purpose deplate, knife, andfodt, all constructed su'bstantially as and for .the purposes herein setforth.

In testimony that we claim the foregoing we have hereunto set our handsthis 16th day of June, 1875.
